|discussion=<p>Species ca. 12 (1 in the flora).</p><!--
--><p><i>Dasiphora</i> comprises the shrubby cinquefoils, which are well known in the horticultural trade. All species occur in Asia; only <i>D. fruticosa</i> is also native to the flora area. Molecular analysis confirms the distinction of these species from <i>Potentilla</i> (T. Eriksson et al. 1998; M. Lundberg et al. 2009; C. Dobeš and J. Paule 2010), with morphological support provided by the shrubby habit, unique leaflet division, and anther structure (J. Soják 1989). Pentaphylloides Duhamel has been misapplied to this genus (for example, N. H. Holmgren 1997b); that name is based on <i>Potentilla</i> and accordingly not legitimate. Contrary to W. A. Weber and R. C. Wittmann (1996), <i>Dasiphora</i> is not nomenclaturally superfluous; P. A. Rydberg (1898) lectotypified it on P. fruticosa.</p>
